IMPROVEMENT IN MEAT-(SHOPPER-S.

Specification forming part of Letters Patent No. 123,725, dated February13, 1872.

To all whom. it may concern:

Be it known that I, DANIEL Pn'rnns, of Fort Madison, in the county ofLee and State of Iowa, have invented a new and Improved Meat-Chopper andI do hereby declare th at th e following is aiull, clear, and exactdescription thereof, reference being had to the accompanying drawingmaking part of this specification, in which- Figure 1, Plate 1, is afront elevation of the machine. Fig. 2, Plate 1, is a top View. Fig. 3,Plate 1,.is an elevation of one side of the machine. Fig. 4, Plate 1, isa top view ofthe base of the machine. Fig. 5, Plate 2, is a sectiontaken vertically and transversely through the center of the machine.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention relates to certain novel improvements in machines forchopping meat, wherein are employed an adjustableintermittently-rotating chopping-block, a series of knives, which areoperated by cranks, and so arranged and guided that they perform drawingcuts, and also a scraper, which will direct the material inwardly fromthe corner of the chopping-block so as to be constantly brought beneaththe knives, as will be hereinafter eX- plained.

The following description of my invention will enable others skilled inthe art to Vunderstand it. 'f'

In the accompanying drawing, A represents an upright frame, ofrectangular form, which is erected upon a quadrangular base, B. Theinner upper edges of the bars composing this base B have inclineddepressions b' formed into them, on the inclines of which the ends offour arms of a cross-frame, D, rest, so that by turning the latter aboutits center it will rise or descend. By means of a bolt, which is passedthrough one of the arms, and also through a curved slot, c, the frame Dcan be fixed rigidly to its frame B after it is properly adjusted. Nearthe extremities of the arms of frame D are anti-friction wheels b, onwhich is support ed a cylindrical chopping-block, O, which is fittedinto a metallic shell having ratchet-teeth c formed on its upperhorizontal edge. The center pin a of the block C is received into a hubformed in the center of the cruciform frame D; and directly above thispin a a center post, O', of cylindrical form, rises from thechopping-surface of the block, so as to prevent the accumulation of meatin the center of the block, where it would be out of the way of thechoppers j. N represents a beveled and tapering olea-rer, which liesclosely in the curve formed by the block G and that portion of its shellwhich rises above its surface, and which is held in its place by a rod,a, fastened to one of the uprights of the frame A. This clearer scrapesthe meat from the extreme circumference of the block and directs itbeneath the choppers j. Above the chopping-block, and having itsbearings in the uprights of frame A, is a driving-shaft, f, on theextreme outer edge of which is a crank, 7c. There are two eccentricskeyed on shaft f, which communicate alternate backward and forwardmovements to `two pawls, c e, through the medium of anglelevers e1 eland connecting-rod e2 e2. The free hooded ends of the pawls e c are helddown upon the ratched teeth c of the chopping-block case by springswhich are fastened to frame A. By these means the chopping-block and itscase receive together a slow intermittent rotary motion when the shaft fis turned, which `keeps the meat on the block constantly moving beneaththe choppers. Above the shaft f, but on the front side of the frame A,is another shaft, g, which receives motion from shaft j through a largespur-wheel, f1, and a pinion, f2. This shaft g has four cranks formed onit corresponding to the four chopping-knives j, and to each crank aknife-staff, h, is attached by a journal-box and straps. Each staffpasses between the bars of a hinged rack, i, and below this rack eachstaff is connected by a link, t, to a frame, G, as shown in Fig. 5. Therack i is composed of a number of parallel bars secured to a bar, G2,which is hinged at s s to the frame G. The bars of this rack serve asguides for the staffs of the choppers, and prevent their displacementlaterally. The hinging of the rack allows it to be thrown back whenaccess below it is desired.

It will be seen th at the crank-motion ,together with the link-motion ofthe knife-staff, causes the knives to perform a draw-cut on the meat ateach downward stroke. It will also be seen that the chopping-block andits case can be.

readily adjusted up to the knives by simply ""turning' the frame D, thusproviding for the Wearing away of the surface of said block.

Having described inynvention, what I claim as new, and desire to secureby Letters Patcnt, is-

l. The combination ofthe choppers h j, crankshaft g, frame G, and linkst t, arranged and operating substantially as described.

2. The combination of the hinged guide-bars or rack i and the choppers hj, arrangedl and operating as described.

3. The combination of the frame D, adjustable vertically in the mannerdescribed, chopping-block C, and choppers 71,3', arranged and operatingas set forth.

4. The clearerNn, constructed andoperating as described, in combinationwith the choppers hj, chopping-block C, and post C', arranged andoperating substantially as described.

5. The combination of the set of pawls e 0,1
